Organic Chemistry: Enantiomers and Diastereomers


Summary: Enantiomers and Diastereomers


Absolute configuration  -  The arrangement of atoms about a stereocenter, denoted in an unambiguous way.
Achiral  -  An object thatis superimposable on (identical to) its mirror image.
Cahn-Ingold-Prelog  -  Convention used to assign priorities to substituent groups. Used for designating (R)/(S) configurations.
Chiral  -  An object that is not superimposable on its mirror image.
Diastereomer  -  Stereoisomers that are not enantiomers.
Enantiomer  -  Stereoisomers that are non-superimposable mirror images.
Meso  -  A compound that contains multiple stereocenters but is achiral due to an internal plane of symmetry.
Stereocenter  -  Short for stereogenic center. A component of a molecule that gives rise to stereoisomerism. Often a carbon atom attached to four distinct groups.
Stereochemistry  -  The spatial arrangement of atoms in molecules, and the study of how chiral molecules behave in chemical environments.
